This example lab uses multiple unit tests to test the KiloToPounds() function. Complete a program that takes a weight in kilograms as input, converts the weight to pounds, and then outputs the weight in pounds. 1 kilogram = 2.204 pounds (lbs). Ex: If the input is: 10 the output is: 22.04 lbs Note: Your program must define the function double KiloToPounds (double kilos) The program below has an error in the KiloToPounds() function. 1. Try submitting the program for grading (click "Submit mode", then "Submit for grading"). Notice that the first two test cases fail, but the third test case passes. The first test case fails because the program outputs the result from the Kilo ToPounds() function, which has an error. The second test case uses a Unit test to test the Kilo ToPounds() function, which fails. 2. Change the Kilo ToPounds() function to multiply the variable kilos by 2.204, instead of dividing. The return statement should be: return (kilos * 2.204); Submit again. Now the test cases…
